When to use

Mechanical anchors suit fixings that must be loaded at once, temporary works and light to medium loads with generous edge distance. Expansion anchors push against the hole wall, so they need more edge distance and spacing than bonded anchors.

When to use a chemical anchor
Cast-in, chemical or mechanical.
